Cannot find Trial of Sekhemas

This is like my 8th character, I've googled over and over again, I literally cannot find this place. Please someone just tell me what waypoint to teleport to as the game stright up refuses to tell me where to go. I have cleared traitor's passage twice and it is not connected to the trial.

It's there...just a PITA to discover the opening. I just create new instances until it's found a little faster per try.
